Further, the bus bar portion B of the coil C1 is electrically connected (welded) to the lead wire portion L of the other corresponding coil C1 to form U-phase, V-phase and W-phase stator coils. In the present embodiment, the coil C1 has a rectangular shape when the long side portion (first side portion) is viewed from the front, and has an isosceles trapezoidal shape when the short side portion (second side portion) is viewed from the front.

And the surface support portion 11c are formed. The corner support surface 11a is located on the outermost peripheral side of the stator core Sc of the coil C1 in the radial direction, and forms one corner portion (upper side in FIG. 4) connected to the long side portion of one side (left side in FIG. 4). It is formed so as to abut on the outer surface Aco1 of the flat wire W.

That is, the corner support surface 11a, the short side support surface 11b, and the surface support portion 11c are such that when the short side support surface 11b abuts on the outer surface Bo1 of the coil C1, the corner support surface 11a abuts on the outer surface Aco1. Moreover, the inner surface of the surface support portion 11c is formed at the tip end portion of the first coil support member 11 so as to abut the end surface of the coil C1 along the outer surface Bo1.

第２コイル支持部材１２は、ベース部材１５によりｚ軸方向に沿って移動自在に支持されており、その先端部には、図４に示すように、コーナー支持面１２ａと、短辺支持面１２ｂと、表面支持部１２ｃとが形成されている。コーナー支持面１２ａは、コイルＣ１のステータコアＳｃの径方向における最外周側に位置することになる一方（図４における左側）の長辺部に連なる他方（図４における下側）のコーナー部を形成する平角線Ｗの外側面Ａｃｏ２に当接するように形成されている。また、短辺支持面１２ｂは、当該外側面Ａｃｏ２を含むコーナー部に連なる短辺部を形成する平角線Ｗの外側面Ｂｏ２に当接するように形成されている。更に、表面支持部１２ｃは、外側面Ｂｏ２に沿ったコイルＣ１の端面（平角線Ｗの表面）に当接するように形成されている。すなわち、コーナー支持面１２ａ、短辺支持面１２ｂおよび表面支持部１２ｃは、短辺支持面１２ｂがコイルＣ１の外側面Ｂｏ２に当接した際に、コーナー支持面１２ａが外側面Ａｃｏ２に当接し、かつ表面支持部１２ｃの内面が外側面Ｂｏ２に沿ったコイルＣ１の端面に当接するように第２コイル支持部材１２の先端部に形成されている。 The second coil support member 12 is movably supported by the base member 15 along the z-axis direction, and has a corner support surface 12a and a short side support surface 12b at the tip thereof, as shown in FIG. And the surface support portion 12c are formed. The corner support surface 12a is located on the outermost peripheral side of the stator core Sc of the coil C1 in the radial direction, and forms the other corner portion (lower side in FIG. 4) connected to the long side portion of one (left side in FIG. 4). It is formed so as to abut on the outer surface Aco2 of the flat wire W. Further, the short side support surface 12b is formed so as to abut on the outer surface Bo2 of the flat wire W forming the short side portion connected to the corner portion including the outer surface Aco2. Further, the surface support portion 12c is formed so as to abut the end surface (surface of the flat wire W) of the coil C1 along the outer surface Bo2. That is, the corner support surface 12a, the short side support surface 12b, and the surface support portion 12c are such that when the short side support surface 12b abuts on the outer surface Bo2 of the coil C1, the corner support surface 12a abuts on the outer surface Aco2. Moreover, the inner surface of the surface support portion 12c is formed at the tip end portion of the second coil support member 12 so as to abut the end surface of the coil C1 along the outer surface Bo2.

図３に示すように、第１および第２コイル支持部材１１，１２は、連動機構１６を介して互いに連結されている。連動機構１６は、第２コイル支持部材１２に向けて延在するように第１コイル支持部材１１に固定された第１ラックＲ１と、第１コイル支持部材１１に向けて延在するように第２コイル支持部材１２に固定された第２ラックＲ２と、ベース部材１５により回転自在に支持されると共に第１および第２ラックＲ２の双方に噛合する平歯車Ｇ０とを含む。更に、第１コイル支持部材１１には、制御装置１００により制御されるエアシリンダ１７が連結されている。エアシリンダ１７は、ベース部材１５に対して固定されており、第１コイル支持部材１１をｚ軸方向に進退移動させる。 As shown in FIG. 3, the first and second coil support members 11 and 12 are connected to each other via an interlocking mechanism 16. The interlocking mechanism 16 has a first rack R1 fixed to the first coil support member 11 so as to extend toward the second coil support member 12, and a first rack R1 so as to extend toward the first coil support member 11. It includes a second rack R2 fixed to the two-coil support member 12 and a spur gear G0 that is rotatably supported by the base member 15 and meshes with both the first and second racks R2.

エアシリンダ１７により第１コイル支持部材１１が第２コイル支持部材１２側（図３中下方）に移動させられると、第１ラックＲ１が図中下方に移動し、それに伴って平歯車Ｇ０が一方向に回転すると共に、第２ラックＲ２が図中上方に移動する。これにより、第１および第２コイル支持部材１１，１２は、エアシリンダ１７および連動機構１６によりｚ軸方向に沿って互いに接近するように移動させられる。また、エアシリンダ１７により第１コイル支持部材１１が第２コイル支持部材１２とは反対側（図３中上方）に移動させられると、第１ラックＲ１が図中上方に移動し、それに伴って平歯車Ｇ０が他方向に回転すると共に、第２ラックＲ２が図中下方に移動する。これにより、第１および第２コイル支持部材１１，１２は、エアシリンダ１７および連動機構１６によりｚ軸方向に沿って互いに離間するように移動させられる。すなわち、第１および第２コイル支持部材１１，１２は、エアシリンダ１７および連動機構１６（接近離間機構）によりｚ軸方向に沿って互いに接近離間させられる。 When the first coil support member 11 is moved to the second coil support member 12 side (lower in FIG. 3) by the air cylinder 17, the first rack R1 moves downward in the figure, and the spur gear G0 is moved accordingly. As it rotates in the direction, the second rack R2 moves upward in the figure. As a result, the first and second coil support members 11 and 12 are moved by the air cylinder 17 and the interlocking mechanism 16 so as to approach each other along the z-axis direction. Further, when the first coil support member 11 is moved to the side opposite to the second coil support member 12 (upper in FIG. 3) by the air cylinder 17, the first rack R1 moves upward in the figure, and accordingly. As the spur gear G0 rotates in the other direction, the second rack R2 moves downward in the figure. As a result, the first and second coil support members 11 and 12 are moved by the air cylinder 17 and the interlocking mechanism 16 so as to be separated from each other along the z-axis direction. That is, the first and second coil support members 11 and 12 are brought close to each other along the z-axis direction by the air cylinder 17 and the interlocking mechanism 16 (approaching / separating mechanism).

It is formed so as to abut. The second coil receiving portion 132 corresponds to the surface of the flat wire W forming the long side portion of the other (left side in FIG. 5) on the innermost peripheral side of the coil C1 in the radial direction and the corner portion connected to the long side portion. It is formed so as to be in contact with the first coil receiving portion 131, and is arranged at a distance from the first coil receiving portion 131. Further, the second coil receiving portion 132 is formed wider than the second coil receiving portion 131, and has a short side length (coil width) longer than that of the coil C1. Coil C2 (second coil, in the drawing). , See broken line) can receive the end face along the long side. That is, the second coil receiving portion 132 is the surface of the flat wire W forming a long side portion of the coil C2 on the innermost peripheral side (left side in FIG. 5) of the coil C2 and a corner portion connected to the long side portion. It is formed so as to come into contact with. Further, a core 13a is arranged between the first coil receiving portion 131 and the second coil receiving portion 132. As shown in FIGS. 4 and 5, the core 13a is a flat wire forming a long side portion of one of the innermost peripheral sides (left side in FIG. 4 and right side in FIG. 5) of the coils C1 and C2 in the radial direction. It is installed close to the first coil receiving portion 131 so as to come into contact with the inner side surface Ai1 of the above.

加えて、組付ハンド１０は、図５に示すように、第３コイル支持部材１３をベース部材１５に対して移動させてコイルＣ１，Ｃ２を変形させるコイル変形機構１８を含む。コイル変形機構（移動機構）１８は、ｘｙ平面に沿って延在するように第３コイル支持部材１３に固定されたラックＲ３や、ラックＲ３に噛合する平歯車Ｇ３、ベース部材１５に固定されると共に制御装置１００により制御されて平歯車Ｇ３を回転駆動するモータＭ等を含む。コイル変形機構１８のモータＭにより平歯車Ｇ３を回転駆動することで、ラックＲ３と共に第３コイル支持部材１３をベース部材１５に対してｘｙ平面に沿って往復移動させることができる。ここで、組付ハンド１０の第１および第２コイル支持部材１１，１２は、ベース部材１５に対してｚ軸方向以外の方向には移動不能である。従って、コイル変形機構１８を作動させることにより、図５からわかるように、第１および第２コイル支持部材１１，１２と第３コイル支持部材１３とをコイルＣ１，Ｃ２の短辺部の延在方向に相対移動させることが可能となる。 In addition, as shown in FIG. 5, the assembly hand 10 includes a coil deformation mechanism 18 that moves the third coil support member 13 with respect to the base member 15 to deform the coils C1 and C2. The coil deformation mechanism (movement mechanism) 18 is fixed to the rack R3 fixed to the third coil support member 13 so as to extend along the xy plane, the spur gear G3 meshing with the rack R3, and the base member 15. Along with this, a motor M or the like that is controlled by the control device 100 to rotate and drive the spur gear G3 is included. By rotationally driving the spur gear G3 by the motor M of the coil deformation mechanism 18, the third coil support member 13 can be reciprocated with respect to the base member 15 along the xy plane together with the rack R3. Here, the first and second coil support members 11 and 12 of the assembly hand 10 are immovable with respect to the base member 15 in directions other than the z-axis direction. Therefore, by operating the coil deformation mechanism 18, as can be seen from FIG. 5, the first and second coil support members 11 and 12 and the third coil support member 13 are extended on the short sides of the coils C1 and C2. It is possible to move relative to the direction.

次に、コイル装着装置１の動作について説明する。 Next, the operation of the coil mounting device 1 will be described.

組付ハンド１０によりコイルＣ１またはＣ２をステータコアＳｃの複数のティースＴに組み付ける際、コイル装着装置１の制御装置１００は、図５に示すように、保管箇所のコイルＣ１またはＣ２の最内周側の端面に、第３コイル支持部材１３の第１および第２コイル受け部１３１、１３２の表面を当接させるように移動機構５０を制御する。この際、第１コイル受け部１３１は、コイルＣ１またはＣ２のステータコアＳｃの径方向における最内周側に位置することになる一方（図５における右側）の長辺部等を形成する平角線Ｗの表面に当接する。また、第２コイル受け部１３２は、コイルＣ１またはＣ２の最内周側の他方（図５における左側）の長辺部等を形成する平角線Ｗのの表面に当接する。更に、第３コイル支持部材１３の中子１３ａは、コイルＣ１またはＣ２の最内周側の一方（図５における右側）の長辺部を形成する平角線の内側面Ａｉ１に当接する。 When the coils C1 or C2 are assembled to the plurality of teeth T of the stator core Sc by the assembling hand 10, the control device 100 of the coil mounting device 1 is the innermost peripheral side of the coils C1 or C2 at the storage location, as shown in FIG. The moving mechanism 50 is controlled so that the surfaces of the first and second coil receiving portions 131 and 132 of the third coil supporting member 13 are brought into contact with the end faces of the third coil supporting member 13. At this time, the first coil receiving portion 131 is located on the innermost peripheral side of the stator core Sc of the coil C1 or C2 in the radial direction, while the flat wire W forming the long side portion (right side in FIG. 5) is formed. Contact the surface of. Further, the second coil receiving portion 132 abuts on the surface of the flat wire W forming the long side portion or the like of the other (left side in FIG. 5) on the innermost peripheral side of the coil C1 or C2. Further, the core 13a of the third coil support member 13 comes into contact with the inner side surface Ai1 of the flat wire forming the long side portion of one of the innermost peripheral sides (right side in FIG. 5) of the coil C1 or C2.

次いで、制御装置１００は、第１コイル支持部材１１を第２コイル支持部材１２側（図３中下方）に移動させるようにエアシリンダ１７を制御し、第１および第２コイル支持部材１１，１２をｚ軸方向に沿って互いに接近させる。第２コイル支持部材１２に対して接近した第１コイル支持部材１１（コーナー支持面１１ａおよび短辺支持面１１ｂ）は、図６および図７に示すように、コイルＣ１またはＣ２のステータコアＳｃの径方向における最外周側に位置することになる一方（図６および図７における左側）の長辺部に連なる一方（図６および図７における上側）のコーナー部を形成する平角線Ｗの外側面Ａｃｏ１と、外側面Ａｃｏ１を含むコーナー部に連なる短辺部を形成する平角線Ｗの外側面Ｂｏ１とを支持する。また、第１コイル支持部材１１に対して接近した第２コイル支持部材１２（コーナー支持面１２ａおよび短辺支持面１２ｂ）は、コイルＣ１またはＣ２のステータコアＳｃの径方向における最外周側に位置することになる一方（図６および図７における左側）の長辺部に連なる他方（図６および図７おける下側）のコーナー部を形成する平角線Ｗの外側面Ａｃｏ２と、外側面Ａｃｏ２を含むコーナー部に連なる短辺部を形成する平角線Ｗの外側面Ｂｏ２とを支持する。 Next, the control device 100 controls the air cylinder 17 so as to move the first coil support member 11 to the second coil support member 12 side (lower in FIG. 3), and the first and second coil support members 11, 12 Are brought closer to each other along the z-axis direction. The first coil support member 11 (corner support surface 11a and short side support surface 11b) approaching the second coil support member 12 has a diameter of the stator core Sc of the coil C1 or C2 as shown in FIGS. 6 and 7. The outer surface Aco1 of the flat wire W forming the one (upper side in FIGS. 6 and 7) corner portion connected to the long side portion on the one side (left side in FIGS. And the outer surface Bo1 of the flat wire W forming a short side portion connected to the corner portion including the outer surface Aco1. Further, the second coil support member 12 (corner support surface 12a and short side support surface 12b) approaching the first coil support member 11 is located on the outermost peripheral side of the stator core Sc of the coil C1 or C2 in the radial direction. The outer surface Aco2 and the outer surface Aco2 of the flat wire W forming the corner portion of the other side (lower side in FIGS. 6 and 7) connected to the long side portion of one side (left side in FIGS. 6 and 7) are included. It supports the outer surface Bo2 of the flat wire W forming the short side portion connected to the corner portion.

これにより、第１から第３コイル支持部材１１−１３によりコイルＣ１またはＣ２をしっかりと保持してステータコアＳｃのティースＴに組み付けていくことが可能となる。すなわち、コイルＣ１またはＣ２の一方の長辺部側でのみ最内周側の長辺部および最外周側のコーナー部を保持するように第１から第３コイル支持部材１１−１３を構成することで、これらの第１から第３コイル支持部材１１−１３によって互いに異なる短辺長を有するコイルＣ１，Ｃ２を保持してステータコアＳｃのティースＴに組み付けていくことができる。 As a result, the coils C1 or C2 can be firmly held by the first to third coil support members 11-13 and assembled to the teeth T of the stator core Sc. That is, the first to third coil support members 11-13 are configured so as to hold the long side portion on the innermost peripheral side and the corner portion on the outermost outer peripheral side only on one long side portion side of the coils C1 or C2. Then, the coils C1 and C2 having different short side lengths can be held by the first to third coil support members 11-13 and assembled to the teeth T of the stator core Sc.

ティースＴに対するコイルＣ１またはＣ２の組み付けに際し、コイル装着装置１の制御装置１００は、組付ハンド１０が対象となるティースＴに接近するように移動機構５０を制御すると共に、第１および第２コイル支持部材１１，１２と第３コイル支持部材１３とをコイルＣ１，Ｃ２の短辺部の延在方向に相対移動させるようにコイル変形機構１８のモータＭを制御する。コイル変形機構１８により第１および第２コイル支持部材１１，１２に対して第３コイル支持部材１３が移動させられると、図８に示すように、コイルＣ１またはＣ２の最内周側の一方（図８における右側）の長辺部を形成する平角線Ｗが中子１３ａにより押圧されて第３コイル支持部材１３と共にｘｙ平面に沿って移動する。これに対して、コイルＣ１またはＣ２の最外周側の一方（図８における右側）の長辺部を形成する平角線Ｗのｘｙ平面に沿った方向の移動は、第１および第２コイル支持部材１１，１により規制される。 When assembling the coil C1 or C2 to the tooth T, the control device 100 of the coil mounting device 1 controls the moving mechanism 50 so that the assembling hand 10 approaches the target tooth T, and the first and second coils. The motor M of the coil deformation mechanism 18 is controlled so that the support members 11 and 12 and the third coil support member 13 are relatively moved in the extending direction of the short side portions of the coils C1 and C2. When the third coil support member 13 is moved with respect to the first and second coil support members 11 and 12 by the coil deformation mechanism 18, as shown in FIG. 8, one of the innermost peripheral sides of the coils C1 or C2 ( The flat wire W forming the long side portion (right side in FIG. 8) is pressed by the core 13a and moves along the xy plane together with the third coil support member 13. On the other hand, the movement of the flat wire W forming the long side portion of one of the outermost peripheral sides (right side in FIG. 8) of the coils C1 or C2 along the xy plane is the movement of the first and second coil support members. It is regulated by 11 and 1.

これにより、図８に示すように、第１から第３コイル支持部材１１−１３により保持されている一方（図８における右側）の長辺部の各段の平角線Ｗが短辺部の延在方向に集合すると共に、第１から第３コイル支持部材１１−１３により保持されていない他方の長辺部側の各段の平角線Ｗが短辺の延在方向に拡がるように、コイルＣ１，Ｃ２を斜めに変形させることができる。この際、コイルＣ１，Ｃ２の復元力は、内周側と外周側とで逆向きとなるので（図８における点線参照）、コイルＣ１，Ｃ２が第１から第３コイル支持部材１１−１３により保持されていない他方の長辺部側に移動することはない。これにより、既にステータコアＳｃに組み付けられたコイルＣ１等や当該コイルＣ１等のバスバー部Ｂとの干渉を抑制しながらティースＴにコイルＣ１またはＣ２を組み付けたり、既にコイルＣ１等が組み付けられている２つのティースＴの間に位置するティースＴ（最後のティース）に対してコイルＣ１等を円滑に組み付けたりすることができる。 As a result, as shown in FIG. 8, the flat line W of each stage of the long side portion while being held by the first to third coil support members 11-13 (on the right side in FIG. 8) extends the short side portion. Coil C1 so as to gather in the existing direction and to extend the flat wire W of each stage on the long side side of the other, which is not held by the first to third coil support members 11-13, in the extending direction of the short side. , C2 can be deformed diagonally. At this time, the restoring forces of the coils C1 and C2 are opposite to each other on the inner peripheral side and the outer peripheral side (see the dotted line in FIG. 8). It does not move to the other long side that is not held. As a result, the coil C1 or C2 is assembled to the teeth T while suppressing the interference with the coil C1 or the like already assembled to the stator core Sc or the bus bar portion B of the coil C1 or the like, or the coil C1 or the like is already assembled 2 The coil C1 and the like can be smoothly assembled to the teeth T (last teeth) located between the two teeth T.

以上説明したように、本開示のコイル装着装置１によれば、第１から第３コイル支持部材１１−１３によって互いに異なる短辺長を有するコイルＣ１，Ｃ２を保持することが可能となる。また、コイル変形機構１８により第１および第２コイル支持部材１１，１２と第３コイル支持部材１３とをコイルＣ１等の短辺部の延在方向に相対移動させることで、当該短辺部の長さに拘わらずコイルＣ１，Ｃ２を斜めに変形させることができる。この結果、互いに異なる短辺長を有するコイルＣ１，Ｃ２をステータコアＳｃの複数のティースＴに円滑に組み付けることが可能となる。 As described above, according to the coil mounting device 1 of the present disclosure, the coils C1 and C2 having different short side lengths can be held by the first to third coil support members 11-13. Further, by moving the first and second coil support members 11 and 12 and the third coil support member 13 relative to each other in the extending direction of the short side portion of the coil C1 or the like by the coil deformation mechanism 18, the short side portion can be moved. The coils C1 and C2 can be deformed diagonally regardless of the length. As a result, the coils C1 and C2 having different short side lengths can be smoothly assembled to the plurality of teeth T of the stator core Sc.
